Cape Flattery, the northwesternmost point of the contiguous United States, can be reached from a short walk on boardwalks and trail in Clallam County on the Makah Reservation, Washington. Admire coastal scenery, sea stacks, and surf. Here the Strait of Juan de Fuca joins the Pacific Ocean. Offshore of the Olympic Peninsula, the Olympic Coast National Marine Sanctuary extends from Cape Flattery in the north to Copalis River in the south.
